A power source is a source of power. Most commonly the type of power referred to is: Power (physics), the rate of doing work; equivalent to an amount of energy consumed per unit time. Electric power, the rate at which electrical energy is transferred by an electric circuit; usually produced by electric generators or batteries.

A power source is a device or machine that supplies electric power to a system. You can think of a power source as something that provides energy to electrons in a circuit. There are two common forms of power sources, named after the type of electric current that they produce; direct current (DC) and alternating current (AC).
The main job of a power source is to supple electrical energy to a circuit. This is accomplished in different ways depending on the type of power source.
Voltage Sources
A voltage sourceis a device that can maintain a fixed voltage no matter the load (i.e. resistance) on the circuit. Just like other components, voltage sources are theoretical, ideal versions of a real life system. In the real world, no voltage source is perfectly ideal; for one, voltages supplied always vary with the load, even if just a little. When you tap into the power grid by plugging a device into a wall socket, you aren’t always getting the same exact voltage. The power supplied by ele...
Current Sources
Current sources are the dual of voltage sources. An ideal current source always supplies the same current no matter the circuit or load (i.e. resistance). Just like with voltage sources, no ideal current source exists in real life. However, some examples of pretty goodcurrent sources do exist. Current sources can be made from transistors or operational amplifiers. We’ll tackle this subject in our Module on Semiconductors.
This wouldn’t be much of a lesson on power sources if we didn’t at least introduce the concept of electric power. Electric power is measured in the SI unit of the watt, which is the amount of energy supplied (in Joules) per second. In other words, power is the rate at which energy is supplied to the circuit. In order to get the total energy supplie...
An electrical load is a component that consumes electric power. For instance, any time you plug a device into a wall socket, your device functions as a load because it consumes power supplied by the power grid (aka mains). In a battery powered device, the battery supplies the energy while the rest of the device functions as the load. Electrical loa...
As the name suggests, a power source is any type of electrical or mechanical device that is capable of delivering an electrical load and/or a back-up power supply. This source of power must also address specific parameters that are ultimately determined by the destination device: [1] Voltage. Current. Frequency.
